## Which issue does this PR close?
<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases. You can
link an issue to this PR using the GitHub syntax. For example `Closes #123`
indicates that this PR will close issue #123.
-->
- Relates to #20427 .
## Rationale for this change
<!--
Why are you proposing this change? If this is already explained clearly in
the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand your
changes and offer better suggestions for fixes.
-->
The existing `in_list` benchmarks only cover the static filter path
(constant literal lists), which uses HashSet lookup. There are no benchmarks
for the dynamic evaluation path, triggered when the IN list contains
non-constant expressions such as column references (e.g., `a IN (b, c, d)`).
Adding these benchmarks establishes a baseline for measuring the impact
upcoming optimizations to the dynamic path. (see #20428).
## What changes are included in this PR?
<!--
There is no need to duplicate the description in the issue here but it is
sometimes worth providing a summary of the individual changes in this PR.
-->
Add criterion benchmarks for the dynamic IN list evaluation path:
- `bench_dynamic_int32`: Int32 column references, list sizes [3, 8, 28] ×
match rates [0%, 50%, 100%] × null rates [0%, 20%]
- `bench_dynamic_utf8`: Utf8 column references, list sizes [3, 8, 28] ×
match rates [0%, 50%, 100%]
## Are these changes tested?
<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code
If tests are not included in your PR, please explain why (for example, are
they covered by existing tests)?
-->
Yes. The benchmarks compile and run correctly. No implementation code is
changed.
## Are there any user-facing changes?
<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->
<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
